Composite insulators can be divided into: line composite insulators and power station, electrical composite insulators. It can also be divided into rod-shaped suspension composite insulators, pin-type composite insulators, cross-arm composite insulators, pillar composite insulators, wind-proof and partial composite insulators, etc. The detection principle of composite insulator manufacturers is based on the water jet classification method.
Based on digital image processing technology, the composite insulator can objectively determine the hydrophobic state of the composite insulator by extracting grayscale information such as information entropy, seed rate, and spectral amplitude mean value of the hydrophobic image, and the shape coefficient and area percentage of water droplets or water traces. Discrimination, the function of charging to detect the hydrophobicity of various composite insulators.
